Answer:
[tex]\frac{22}{3}[/tex] = b
or
7[tex]\frac{1}{3}[/tex] = b
(they are the same value, just different ways of writing it)
Step-by-step explanation:
4 = -[tex]\frac{2}{3}[/tex] (5) + b
simplify
4 = -[tex]\frac{10}{3}[/tex] + b
now use inverse operations
4 = -[tex]\frac{10}{3}[/tex] + b
+[tex]\frac{10}{3}[/tex] +[tex]\frac{10}{3}[/tex]
[tex]\frac{22}{3}[/tex] = b
